"To start, I put in for an emergency call to Freschi and was told they would call me 30 minutes before. They never called me back. Freschi sucks!!!I I also put in a request on HomeAdvisor on Thursday night and was given Global Warming Heating and Air as one of their verified contractors. I got a call at 7am from Rudy. I called back around 830am and we made an appointment for 1130am. He showed up at 1105am and quickly diagnosed the problem. He recommended replacing the furnace(which houses the blower assembly) due to the cost of repairs and its 17 year old condition. He didn t try to up sell me for an entire new system. He said my AC is working well so there s no need to replace it. I decided to replace the furnace and he said he d be back around 130pm. Rudy and his crew were back by 1pm. From the start of demo to it running again was less than 2 hours. Rudy s customer service is top notch!! From now on, I will only be calling Global Warming Heating and Air. I can t say enough good things about Rudy s business ethics and timeliness. A+++++"

Customers say: Super punctual

"Wonderful, I couldn't have had a better experience. I called yesterday because I had a leak under my bathroom sink. My call was answered immediately, and professionally, and when I asked for a certain window of opportunity due to my odd work schedule for the following day I was easily accommodated. The nicest young man came, right on time, and quickly diagnosed the problem. He had two options of repair, one being much easier and less time consuming (i.e. Less expensive), which he tried first, and it worked! He was done in about 15 minutes, and although you pay a flat service fee I think it was absolutely worth every penny. He thoroughly explained why I had the leak, and what the problem was which was very professional, as well."

"Excellent all around. One Hour, the other Marin county heating and air conditioning company tried to rush me into using them at a price that was 2x over market. No rationale for this at all and they just wanted to soak me for a huge price increase. Moore came in at the correct price and no pressure."

"Matt arrived on time & fixed duct leak above furnace & water tubing to drain water reinserted & glued. Also got 2 ceiling filters for me unasked & put new filter in. Very reasonable price for labor & supplies. Previous Dependable Heating & Air company sent 2 people who insisted I replace entire furnace and ducts up to roof vent & wouldn t fix simple duct water leak. Admittedly my furnace is old but still working fine. Will never use Dependable again. Matt didn t pressure me to replace furnace & give me a quick $ amount with no pressure. Nice guy. Matt Kazen was wonderful & will definitely use his company again for heating & air conditioning needs."

"Jaleel Porter from Bell Brother's Heating and Air, Inc. came to the house to install and trouble shoot the installation of two Ecobee Thermostats. We prepaid Best Buy's Geek Squad to installed them but their electrician was not able to install them properly. The job was abandoned by Geek Squad leaving some HVAC wiring mixed up and at least one wire was not connected properly. Jaleel Porter was courteous and has represented his company extremely well. He came wearing protective mask and shoe coverage. He was knowledgeable about the product that he installed. He was also informative about any general and specific HVAC questions and maintenance issues. Moreover, he was also punctual and cordial in communicating how the service works. He was also patient and helpful in teaching us the settings and operations of the system using our apps. He did not leave the premises until everything was functioning properly. Finally, There were no "surprises" and the price was reasonable and competitive."

"My AC stopped working last November, and since then i had 4 contractors i called to fix it, i was turned down by everyone. i called Tyndall and peter came out and talked about it with me, actually troubleshot it, and 2 days later had parts and fixed it. i would give them 6 stars if i could. im so glad to have my ac running again. my recommendation, if you want something done, call Tyndall, because the rest of the contractors seem to just say its not fixable and leave without even looking at it. these guys were the first people that listened, then looked at the unit before declining service, and then actually fixed it. 10/10 great job and thank you."

FAQs for air conditioning projects in Vallejo, CA

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
